The 1983 Annual Meeting of the Iowa Academy of Science on Luther Campus in Decorah provided an excellent opportunity for considering the "Iowa Driftless Area," a region of scenic beauty and unusual scientific diversity. This rugged landscape dominated by bedrock has undergone weathering and erosion longer than any other region of the state. The term "Driftless Area" originated from an early geologic interpretation that a portion of northeastern Iowa had been untouched by Pleistocene glaciers.
